Solvent container with a connecter for communicating with a drug vial

Abstract

A solvent container to be used in combination with a drug container or vial, which comprises a flexible container body containing a solvent therein and having a mouth covered with a self-sealing member, a guide capsule having an open end sealed by a sealing member and being removably mounted on the mouth of the container body; and a double-pointed hollow needle having a sharp piercing edge at each end and being slidably arranged in the guide capsule to constitute a means for communicating the container body with the drug vial in cooperation with the guide capsule.

What is claimed is: 
     
       1. A solvent container with a means for communicating with a drug vial, comprising: a flexible container body containing a solvent and having a mouth covered with a self-sealing means;   a guide capsule having an open end at one end and being removably mounted on the mouth of said flexible container body at the other end, said open end being sealed by a sealing member prior to insertion of a drug vial;   a double-pointed needle having a sharp piercing edge at each end and a hub at its central part, said needle being slidably arranged in said guide capsule to constitute a means for communicating with a drug vial in cooperation with said guide capsule;   an inner wall of said guide capsule having one or more vertical guide grooves for holding said double-pointed needle and for guiding said double-pointed needle towards the mouth of said flexible container, said guide capsule having a partition wall with a hole for insertion of the piercing edge of said double-pointed needle into said mouth of said container body through said self-sealing means; and   wherein said guide grooves extend above and below said hub and extend to said partition wall.   
     
     
       2. The solvent container claimed in claim 1 wherein said hub has arms provided at free ends thereof and adapted to be held in the guide grooves of the guide capsule. 
     
     
       3. The solvent container claimed in claim 2 wherein each guide groove of said guide capsule is provided with a stepped portion on which the arms of the hub are rested to hold said needle in place until a load applied to the needle exceeds a predetermined value. 
     
     
       4. The solvent container claimed in claim 2 wherein the hub of the hollow needle is provided with a means for prevention of kickbacks of a drug vial caused by the elasticity of said self-sealing means. 
     
     
       5. The solvent container claimed in claim 2 wherein the partition wall of said guide capsule has a means for preventing said double-pointed needle from kickbacks caused by the elasticity of said self-sealing means. 
     
     
       6. The solvent container claimed in claim 2 wherein the guide capsule is provided in its guide groove with a projection for preventing an upward movement of the double-pointed needle, which may occur after piercing the double-pointed needle into the self sealing means of the container body.
